I kinda figured it was a comparison...lol...just in case some one else was reading and got the idea....just want to make it clear......laffs.....anyway...yes, you want aquarium salt(sodium chloride) if will work better and at a little higher dose since you are dealing with two different parasites in a later stage...just watch for tolerance and if you note distress decrease the salt...left untreated too long it can be fatal.....they can go into shock.....

Well, good news. The water temp has already risen to 80* just from the heating pad! YAY! But how do I keep an eye on it overnight? I can't exactly wake up every single hour. Also, she still isn't eating. Will she be okay for a while? She just freaks out every time I try to feed her.

Maybe, if the heating pad is making the QT tank too warm, you could sit the QT tank just a bit off of the pad..... experiment a little to find the right spot to keep it a bit stable at the temp you want. Good luck and hope your fishie gets better soon!

It's working perfectly fine. Like you suggested, I have a piece of plastic (half of a folder), and a towel between the pad and the QT cups. It's going great so far. I put it on medium during the night so it didn't get to hot, which worked nicely.

UPDATE: A TON of the Ich has already dropped off. It seemed like there were at least 100 white things floating in and sitting at the bottom of the cup. Somehow, the water got up to around 90* (EEK), so I took the cup off of the pad for a while. When I switched her to the other cup, she jumped out of the cup and ended up on the floor. But she seems fine now. She's laying on her leaf now. She seems a bit more active and spunky. OFL, I cannot thank you enough for your advice. I'm in tears because I'm so happy. Also, now I know how to heat her tank until I get a heater. I also turned the pad down to medium so it will cool down a bit before I put her cup back on it. I also rinsed my net thoroughly with HOT water, and put it on a towel to dry, along with the first cup she was in. I also have the main hospital tank drying. I had already dried her normal 3 gallon already. I think she will make a full recovery!
